Now I don't know about you, but that's a hell of a lot better and there's little to no loss of detail. If you had the time, you could color-correct every shot in the trilogy to make it look just awesome, and maybe even do some dust-removal. Personally I'd just color-correct, I don't mind the dust at all. If you'd do that, first I'd strongly suggest correcting not frame-by-frame but shot-by-shot. For example, put all the frames in one shot into the same Photoshop file and color-correct them all at the same time, basically using the worst-looking frame in the shot as your guide. Second, I could help you out if you want; you could send me some shots via e-mail and I could send the corrected ones back, etc. The biggest problem I have with ANH is sometimes faces get quite red, in ESB there are some shots that are just off, and in ROTJ there are MANY shots that are way too bright, where the black doesn't match the black of the letterbox (most notably in the Vader-Luke duel while Luke is hiding and before he gets really P.O.'d about Vader mentioning Leia, if I remember correctly) and a lot of blue haze around stars.
Like I said, I'd be more than happy to help out if you want. The capture looks to be really good, just needs a little tweaking is all.
